Abstract
Advanced optical fuze (OF) technology based on high-performance optoelectronic sensor is developed for munitions applications. The compact and robust design of the OF employed high-power vertical-cavity surface-emitting lasers (VCSELs), the metal-semiconductor-metal photodetectors, SiGe ASIC driver, miniature optics, and the corresponding electronic signal processors. Mounted on the front of the projectile, the laser transmitter sends out a highly collimated beam that is amplitude modulated with a chirped RF signal. The reflected optical signal from the target is picked up by the photoreceiver on the projectile which also has its electrical bias modulated at the same time-dependent operational frequency as the transmitted optical signal. The on-board signal processor heterodynes both transmitted and the delayed optical waveforms and generates an intermediate frequency corresponding to the time delay due to the travel time of the light. Further measurement of the mixed signals yields directly the range information of the target.
